Of all the listeners who call the local radio station on the telephone , 60% are between the ages of 15 and 25. a random number

generator is used to simulate 20 groups represnting the next 6 listeners who will call the radio station, and the simulated data is recorded below.
(2 3 5 9 1 6) (2 5 5 2 4 1) (8 6 3 0 0 6) (9 3 6 0 5 0) (2 0 2 2 7 2) (6 4 6 7 9 4)

(9 1 0 7 7 7) (0 0 8 3 7 8) (9 9 9 5 5 0) (5 2 9 7 8 3) (2 6 3 1 1 7)

(2 5 2 7 3 5) (0 4 9 9 4 0) (4 7 1 3 4 3) (8 0 0 8 3 7) (3 5 1 5 0 2) (3 7 7 2 5 8)

(7 0 7 3 3 5) (9 1 8 7 4 6) (5 1 9 9 7 4)

which of the following describes possible numbers that may be used to represent listeners within and outside of the age range.

A. within: 0-5 outside: 6-10

B. within: 0-4 outside 5-9

C. within: 0-6 outside 7-9

D: within: 0-5 outside 6-9

2. Based on the simulated data, what is the probability that the next 6 listeners that call the radio station are between 15 and 25 yeard of age?

What s the length of the arc for the half circle
Andrej [43]

Answer`Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

Hope that help, at least a bit.

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?
seraphim [82]

21.6 units

Calculate the length of the 2 inclined sides using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 3 ) and (x₂, y₂ ) = (3, 4 )

d = √(3 + 3 )² + (4 - 3)² = √(36 + 1 ) = √37

repeat for (x₁, y₁ ) = (- 3, 3 ) and (x₂, y₂ ) = (3, - 3 )

d = √(3 + 3 )² + (- 3 - 3 )² = √(36 + 36 ) = √72

the vertical side has a length of 7 units

perimeter = √37 + √72 + 7 = 21.6 ( nearest tenth of a unit )

Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to estimate its average number of unoc
Bingel [31]

Answer:

We need a sample size of at least 719

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?

This is at least n, in which n is found when M = 0.3, \sigma = 4.103. So

M = z*\frac{\sigma}{\sqrt{n}}

0.3 = 1.96*\frac{4.103}{\sqrt{n}}

0.3\sqrt{n} = 1.96*4.103

\sqrt{n} = \frac{1.96*4.103}{0.3}

(\sqrt{n})^{2} = (\frac{1.96*4.103}{0.3})^{2}

n = 718.57

We need a sample size of at least 719
